Referring now more particularly to the figures of the drawings, whereinthere is disclosed one illustrative embodiment exemplifying theprinciples of the present invention, Figures 1 and 2 disclose a juicingand. whipping appliance comprising a drive assembly l and a supportingIt will be seen that the drive motor assembly comprises a motor housingifi containing a suitable driving motor and a permanently associatedrigid supporting bracket assembly I6. From the lowerportion of thehousing, projects a pair of drive shafts I8 interengageable withwhipping agitators I9 which may extend into a bowl represented by thedotted lines in Figures 1 and 2.

The driving assembly, as shown more clearly in Figures 1, 2, 7 and 9,comprises a housing having an upper dome-shaped shell 20 and a lowerconcave section 22 providedwith annular side walls and outwardly flangedas at 2li, providing axially facing recesses to receive opposite cornerlmargins of the laminated core 26 of the electric drive motor 28. Inorder to hold the upper and lower shells 20 and 22 axially upon thelaminated core 2B in the position shown in Figure 7, there is providedan annular clamping band 30 extending about the angular flanges 26 asshown in the figure, and having radially extending marginal peripheralflanges 32 oppositely embracing the complementary radially extendingportions of the flanges 2Q. The flanges 32, being disposed outwardly ofthe flanges 2li, oppositely embrace the latter, permanently completingthe housing assembly.

From the foregoing, it will be apparent that the band 30 embraces theshells in the position f shown, terminating in opposed circumferentialextremities 3d projecting radially outwardly in spaced parallelrelationship as indicated by the dotted lines in Figure 1.

Attention is directed to the fact that the projecting lugs orextremities 3ft are restrained by Ya pair of complementary brackets 36conflgurated as show n in Figure and having permanent interlockingengagement with the housing. To this end, each of the brackets comprisesa side wall 38 narrowed at its central portion and cut away or relievedas at 6U (see Figure 10) in a recess complementary in form to theclamping band 3B..

' in a complementary aperture or slot (not shown in detail) in one ofthe shells 2 0 or 22 so that each pair of brackets 36 may merely beclipped into the housing, as shown in Figure 1, after the clamping bandis in position and when so arranged will bear a rigid, fixed angularrelation Y to the housing, adapted to resist any substantialdistortion.l

It will be apparent from the foregoing that with a pair of complementarybrackets 36 engaging the housing on opposite sides of the clamping bandextremities, the latter are permanently retained in the position shown.The brackets are permanently held in the position shown to tension theextremities of the clamping band by a clamping screw d8 projectingtherethrough at aperture 50 and through the lugs 34.

It is though that important simplification of assembly operations willbe apparent to those skilled in the art from a careful consideration ofthe foregoing. Thus, after merely locating the housing shells andclamping band in the position shown, the complementary pair of brackets36v are shifted and interlocked with the housing by shifting the lugslil thrbugh the complementary apertures or slots and applying tensioningmember 58. It will be appreciated that the recesses or housing slots tdreceive the lug portions 46 may preferably be somewhat circumferentiallyelongated within minor limits to facilitate appreciable applica tion oftension through the agency of the clamping fastener 48, It is obviousfrom the fore going that the present construction eliminates the priorcostly and protracted assembly process involving welding and at the sametime positively interlocks the bracket and the housing againstdisplacement in any relative direction. It will be appreciated that thisis of material importance where the weight of the driving assembly mustbe supported in nxed angular re-1 lationship While under appreciableload.

As further shown in Figure 10, each of the brackets 36 is provided withan inwardly projecting rigidifying flange 52 limiting the ap proach ofthe opposed complementary brackets in assembled relation. The oppositeor right hand extremity of each of the brackets 35, as viewed in Figure10, is flared in its plane to provide al1 upper or handle engagingsection all apertured as at 55 to receive a handle attach-- ment pin orfastener 58. The handle portion of the driving assembly comprises amanually engageable handle bracket conveniently shaped for manualengagement at its central portion and having its lower extremityextending betweenthevopposed sheet brackets 36 as shown in Figures 1, 3,4,v 5 and 6. As` clearly shownin these figures, the illustrated fastener58 com prises a pin and bolt applying a permanent clamping force torigidly clamp the handle bracket 60 between flange portions 54.

The upper portion of the handle bracket fili has a surface E2complementarily engaging the dome of the upper surface of the housingshell 20 and fastened by a llster headed fastener i3d.

As clearly shown Ain Figure 7, the fastener en gages the housing at 66and a Washer 68 below the head of the fastener permits the latter toprovide a cylindrical interlocking projection for a purpose which willhereinafter appear more in, detail. From the foregoing it will beobvious that the handle bracket BU has rigid permanent engagement withthe motor housing and the sheet brackets 36 provide a rigid unitaryassentin bly.

Referring more in detail to Figures 7 and 8, it will be seen that themotor 28 is of conventional forrn disposed centrally and axially of thehousing with the drive shaft extending downwardly and bearing at itslower extremity a pinion l0. Pinion 'I0 interengages both of a pair ofgears 'l2 fixed to the upper extremities of the shafts i8. The gears'lil and i2 dise posed within a gear transmission housin' l having acover 'I6 held in position on the housing by fasteners I8 which alsoextend through the lower wall of the housing shell 22 for locating thetransmission housing I4 within the shell. Projecting sleeves or bushings80 on the transmission housing extend downwardly about journal portionsin the shafts I8 and oil sealing co1- lars 82 on the shafts I9 bearagainst the lower faces of the bushings 80 to prevent leakage oflubricant from the transmission housing.

The beater or whipper units I9 couple releasably with the lowerextremities of the shafts I8 by virtue of suitable coupling means shownin Figures l, 2 and 7 comprising a sleeve 84 rigid with the upperextremity of each beater for embracing the lower end of a stub shaft I8.Each l of these shafts is complementarily relieved on opposite sides ofa central axial plane, as clearly shown in Figure '7, for rotationalinterengagement. In other words, each of the shafts is provided withcomplementary radial abutment faces for transmitting rotationalmovement. It should be noted that the beater shaft has a beveled portion86 to facilitate entry of the stub shaft I8 into the recess formed bythe cut away portion. A resilient spring arm 88 fixed to the lowerextremity of sleeve 04 extends thereabove and is apertured-to embracethe shaft I8. By virtue of being tensioned in a lateral direction, theshaft embracing portion accordingly tends to interengage in an annulargroove 80 in the shaft I8. Accordingly, in the position shown, eachbeater is axially latched to the shaft while being interlocked againstrelative rotation and may be readily released by manually shifting thespring latch 88 until its aperture aligns coaxially with shaft I8, whenthe parts may be axially separated.

Provision is made for efllciently Ventilating the drive motor by meansof a fan impeller 92 mounted upon the upper projecting portion of themotor drive shaft. The fan is conflgurated to direct air downwardlywherefore apertures 94 in the upper shell 20 supply a current of airpassing downwardly about the motor and exhausting through lowerelongated slots or apertures 86. I have particularly noted that in manyof the conventional constructions with which I am familiar, theaero-dynamic design is such that the cooling impeller permits the air tocirculate inefiiciently about housing portions requiring no cooling.. Inother words, there is frequently a.

tendency to induce circulation at points remote from the heated portionsof the motor, resulting in ineifectiveness of the cooling system andloss of power. The present invention contemplates the propulsion of allof the cooling air directly against and through the motor. In short, thepresent construction concentrates the direction of the cooling air tothe motor parts which require cooling. To this end. there is provided aninner shell cr' shroud 88, shown in Figures 7, 9 and l1, having annularconical side wall |00 terminating at its lower extremity in an annularshell engaging flange |02 and at its upper extremity in a radiallyextending flange |04. This cowling or shroud is snugly' received withinthe lower portion of the dome-shaped shell 20 and embraces the marginalperiphery of the fan impeller 92. It will be obvious from the foregoingthat the shroud necessitates axially downward flow of all air handled bythe fan blade 92 and directs the air axially upon and through theinterstices of the motor. While I have provided an aperture |06 forpassage of an electrical supply conduit |08, it will be understood thatthe aperture is relatively restricted and is occupied by the conduit |08whereby air leakage is prevented. It will be apparent, moreover, fromthe foregoing that the present construction necessitates axial flow andinhibitsall tendency for the impeller blade to set up radial andperipheral flow of air, whereby the blade efficiently directs all of theair passing successively through apertures 94 and 96 directly againstthe parts to be cooled. A snap switch |09 is mounted on the upperportion of the housing in convenient location for controlling actuationof the motor.

Referring now to the supporting construction I2, this comprises a atbase portion IIO from one side of which extends an upwardly projectingpedestal I2 engageable with the motive drive unit as shown in Figures 1and 3 to 6. As clearly shown in these figures, this letter meanscomprises a pin I I 3 permanently horizontally mounted in the upperextremity of the pedestal and having yjournal portions I|4 extendinglaterally on either side of the pedestal and terminating in headedabutments IIS. The journal portions 4 are adapted to be received inT-shaped slots III in the plate brackets 36 which laterally embrace theupper extremity of the pedestal I I2 on either side thereof. This pinand bracket interengagement provides a fulcrum about which the drivingunit is adapted to swing between the position shown in Figure l and thatillustrated in Figure 5. These two positions permit the fixture to bearranged selectively Within a mixing bowl as shown in Figure l, or in arelatively remote and elevated position to permit removal of the bowl.

The present invention provides for adjustment of the lowermost positionby means of a stop abutment shown more clearly in Figures 3 and 6v andcomprising a bar I20`extending between the two bracket members 36 andwelded or otherwise fastened rigidly in position in the apertures |22(see Figure 10), preferably with the extremities of the bar extendinglaterally outwardly beyond the plates 36 a short distance in view of anobject which will hereinafter appear more in detail. It will be notedthat the bar |20 is relatively close to the fulcrum pin I3 on thepedestal and the upper end of the pedestal is accordingly cut away as at|24 to permit rotational swinging of the vbar |20 with the remainder ofthe motor unit. In the lowered position of the motive drive unit, thebar |20 rests against an inclined face |26 of adjustable abutment member|28 shiftable vertically in a. cornplementary recess |30 provided In thepedestal ||2. The abutment bar or shaft |30 is notched as at |32 with alaterally outwardly facing V- shaped groove or notch extending in adirection normal to the axis of the abutment shaft |28 and providingupper and lower inclined surfaces in planes inclined with respect tosaid axis. Attention is particularly directed to the fact that thisnotch is normally engaged by the conical extremity I 34 of a set screw I36 extending horizontally through the upper portion of the pedestal ||2and threadedly engaged therewith. Since the inclinationof the conicalsurface |34, where it engages the pin |28, is complementary to theinclination of the adjacent pin surface, it will be seen that thebounding planes of the notch |32 and the conical planar surface |34 formcooperating cam portions which coact to control the elevation Vof theinclined abutment surface |26. In other words, as the adjustment screw|36 is threadedly shifted inwardly of the ment upwardly. When the setscrew is shifted 'to the right, as viewed in Figure 3, the pin |28abutment face |38 defining one extremity of the cut away or relievedportion |24 of the pedestal. Particular attention is directed to thefact that in moving angularly with respect to the fulcrum pin H3,the'T-shaped slot ||8 shifts slightly with respect to the fulcrum pin H3to vary the relative location thereof.

It will be obvious from the foregoing that this minor shifting of thefulcrum permits an additional movement of the motor housing suicient tolocate the center of gravity beyond the right hand side of `a vertica1plane passing through the pin ||3 and as viewed in Figures 1 and 5.' Inotherwords, the coaction of the fixed fulcrum pin |13 and the relativelyelongated slot embracing the'pin enables the disposition of the motorhousing under stable conditions in the angularly remote position andwithout necessitating any rundesirable degree of angular movement. Thatist say, the present construction contemplates the coincidental shiftingof the driving member and its fulcrum point in opposite angulardirection whereby they cooperate to shorten the total movement necessaryto bring the member into a position of equilibrium.

While the foregoing description concerns the arrangement of the driveunit in one cooperative relationship with the supporting means andparticularly sui-table for mixing and whipping, the inventioncomprehends the fixed disposition of the same unit ina substantiallyreversed position as indicated in Figures 12 to 18 whereby to facilitatejuicing and similar operations. It will be appreciated from theforegoing that by virtue of the T-shaped slot constructions H8 in thepedestal engaging bracket, the driving unit is freely removable from thepedestal and when inverted in the position shown in Figure 12 is adaptedto receive a transmission housing |42, together with a' julcing reamer|84 and a juice trough |46. Attention is particularly directed toFigures 12 and 18 indicating the manner in which the projecting lugformed by the filister headed fastener 61| is received within acomplement-ary recess |48 in the base ||0 of the supporting unit I2. Itwill be see'n that this interengagement iixedly locates the driving unitin the plane of the base portion H0. Fixed engagement against relativeAvertical and angular movement is provided by means of a locking clip orbracket |50 shown more in detail in Figures 12 and 16. The bracket |50includes a pair of parallel side portions |52 joined by a top webportion |54 and having laterally aligned slots |56 to embrace thelaterally projecting pin portions ||4 of the pedestal. A pair of alignedapertures |58 receive a cooperating threaded fastener and wing nut |60,operative to yieldably tension the side walls |52 grippingly against theside face of the pedestal ||2 when disposed thereover as shown in Figure12.

Attention is particularly directed to the configuration of the oppositeor left hand extremities of the side webs |52 as viewed in the figures,comprising a shouldered portion embodying a horizontal surface |62 andan angularly disposed pedestal, the conical surface |34 rides along theupper surface of the notch |32 to urge the abutdownwardly extendingsurface |64. Stated in other words, these two surfaces cooperate toprovide complementary recesses for receiving the laterally extendingextremities of the pin or bar |20, which extremities have beendesignated in Figures 12 and 17 by the reference numeral |66. Whenreceived by the locking clip as shown in Figure 12, the motor drive unitis effectively restrained from vertical and rearward movement by theabutments |62 and |66. Similarly, all tendency for rotational movementwith respect to the point of engagement with the base 0, and asindicated by the arrows in Figure 12, is likewise resisted. Since thebracket'plates 3B are embraced between the side flanges |52 of the clip,2t will be seen that the unit is held against latera movement.

From the foregoing, it will be apparent that th'e present constructionprovides a very simple and effective means for rigidly locating themotive unit in the position shown.

There is disclosed in Figures 14 and 15 the general construction of thetransmission unit |42, including an outer cylindrical casing |68 havinga lower annular flange |10 adapted to embrace a portion of the motorhousing shell 22. A central transverse partition |12 Within the housing|68 mounts a pair of vertically extending sleeves |14 for receiving thestub extremities of the drive shafts |8 while the partition |12 restsupon the shaft collars 82. It should be particularly noted that one ofthe shafts only engages with one gear of a reduction gear trainindicated in general by the reference numeral |16 disposed within a cagecomprising the partition |12 and an upper partition |18 joined by aplurality of fixed spacer bars |80. The nal gear |82 of the gear trainis rigid with a reamer shaft |84 projecting upwardly through a sleeve|86 secured to the upper partition member |18. Accordingly, it will beseen that the entire transmission assembly including the reamer shaft,journal and sleeve comprises a unit axially disposable within thecylindrical housing |68 and held therein by a plurality o8 fiat headedmachine screws |88. Thus, it will be" apparent that the fasteners |88extend througli the upper wall of the housing |68 to engage the, upperpartition |18 of the transmission unit. As clearly shown ,in thefigures, the non-circular extremity of one of the drive shafts I8engages the initial pinion of the gear train, whereby the reamer shaft|84 is rotated at a relatively reduced predetermined speed when themotor is actuated. The other shaft I8 rotates idly.

The upper surface of the transmission |42 supports the more or lessconventional juice receiving trough |46 containing a strainer |80, andthe reamer |44 separably rotates with the shaft |84 by means of apolygonal coupling sleeve |92 fixed to said shaft and received by acomplementary recess in the reamer.

From the foregoing, it will be apparent that in use lthe present devicemay be employed either as a whipper or juicer, with thedrive shaft meansprojecting either vertically downwardly or upwardly as desired. In theformer arrangement, the T-shaped slot ||8 of the supporting bracket ismerely disposed over the laterally extending fulcrum pin ||3 of thepedestal when the entire drive unit may be swung about the pivot. The

operator has at his disposal the adjustment screw |36 operable topositively determine the elevation of the whippers or beaters withrespect to the bowl, While being enabled to accurately move the entirebeating assembly out of the bowl to a remote position of positivestability.

Transition to a form suitable for juicing is effected simply by removingthe' driving assembly from the supporting means and inverting it uponthe supporting base with a drive shaft extending upwardly, in whichposition the holding clip |50 is applied to clampingly grip the pedestaland the drive unit bracket. The transmission housing and reamer arefreely disposed over the projecting drive shafts to positively connectthe reamer in driving relation to one of the shafts. It is evident thatin either position of use, the parts are rigidly interlocked and held bythe supporting member and thus xedlylocated with respect to thesupporting surface.

From the foregoing, it will be evident that the present inventionsimplifies the construction of appliances of the present class byeliminating the plurality of drive connections conventionally employedto enable a wide variety of adaptations between whipping and juicing. Inother Words, the present invention contemplates the utilization of arelatively simple driving unit from which the driving shaft meansprojects only in one direction. Provision is made to locate the unitbodily in either of a plurality of operative positions with respect to asupporting means which rigidly holds the unit in either position.Accordingly, therefore, I am enabled to employ a driving unit ofrelatively simplified construction employing a novel degree ofcompactness, lightnessrand portability.

It will be further apparent that the present invention provides animproved interassembly of housing and supporting bracket partscontributing to a novel rigidity and permanence of the driving unitstructure and providing a convenient manual handle by which the drivemotor unit may be manipulated when removed from the supporting means.Thus, the present device is adaptable to operation for stirring andagitating while manually held in a manner obviously impractical withless portable devices. Lt should be further noted that the presentinvienton provides a simplified driving construction involving a motorarranged on a vertical axis and supplied with a predetermined air draftapplied directly and (positively through the portions of the motorrequiring cooling.

The present invention further provides an improved simplified oil sealconstruction adapted to retain oil and lubricantwithin the gear chamber.It will be appreciated that in the operation of the present device it isimportant to effectively prevent passage of this lubricant beyond itshousing and into the mixing or whipping zone. To this end, attention isparticularly directed to the sealing construction shown-in Figure 7,wherein the projecting sleeves 80 of the transmission housing 14 whichembrace the shafts I8 are annularly recessed at their lower end toreceive an annular felt washer 20D. While the felt washer thusretained-is effective to resist leakage of oil, I have found that thefelt may sometimes become soaked. Accordingly, therefor/e, attention isdirected to the fact that the oil sealing collars 82 cooperate to trapthe oil within an area or cavity between the collars or cups and theadjacent outer surfaces of the sleeves 80 and to this end each of thecollars or cups 82 is provided with a downwardly projecting cylindricalportion 202 embracing and rigid with the associated shaft I8.Accordingly, therefore, the portion 262 makes a tight sealing fit uponthe shaft therebetween.

I8. A radial wall of the cup 204 extends outwardly from the lowercylindrical portion 202 and terminates in a vertical cylindrical cupportion 206 about the outer walls of the bushing. It is particularlyimportant to note that the cylindrical walls of the cup arespaced asubstantial distance from the bushing providing an appreciable cavitywhich prevents the oil from creeping and thus effectively retains anyexcess lubricant within the cup.

Obviously the foregoing construction provides an appliance capable ofbeing rapidly and efficiently assembled by a few simple assemblyoperations in quantity production.

Obviously the invention is not limited to the specific structuralarrangement disclosed herein, but is capable of other modifications andchanges without departing from the spirit and scope of the presentinvention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
